PATENT OFFICE.

'1 '0 all whom it may concern:

Be it known that I, SIEGMUND BACH- araxn, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Folding Boxes, of which the following is a full, clear, and exact specification.

Hy invention is sible boxes of the general type shown in my granted June 4, 1907. and is designed to remedy a defect which I have found to exist in it and similar boxes.

To illustrate my invention, I annex hereto a sheet of drawings, in which the same reference characters are used to designate identical parts in all the figures, of which,-

Figure 1 is a plan view of one end of a blank for a box embodying my invention; Fig. 2 is a perspective view of one corner of the box, partly erected; Fig. 3 is a perspective view of one end of the box completely. erected; F i 4 is a detail in section on the line 4 4 0 Fig. 3; and Fig. 5 is a perspective view of one end of the box, showing the action of the parts when it is held by the lapped side of that end.

In the specific box shown in myaforesaid blank was, of course, the same in its two halves, and each lapped or narrow side'of it, as itmight be called 7 was substantiallythe same as the lapped side .or end of the blank shown in Fig. 1, except that itv did not have the folding line a". It'consistedof the body or bottom I), together with the preferably plain sides 8,

and the lapped sides 6 with the intervening folding lines 0 and 0, respectively, and the plain sides the lapped sides e had the similar folds, f with the intervening folding lines 0, and the folds f and f had the intervenin diagonal folding lines 0 The lapped sides e had the folds-f with the intervening hori- The corners were folded up when erected, as is shown in Figs. 2 and 3, in dotted lines, with the lapped side the foldin folds F were secured to the lapped sides e by staples or any suitable securing means, about as indicated at 'w in dotted lines. The corner folds and f were caught. under the lapped side folds f and a box was thus concerned with collaphad the triangular corner folds f. with the intervening folding lines 0 while line 0, and the produced that could be readily collapsed or erected as required. It was found, however, that occasionally the boxes would be grasped at the middle of one lapped side, as indicated in Fig. 5, in which case, if the box was heavy, it would be very apt 'to collapse by reason ofthe edges of the folds f pulling out from under the lapped side fold f thus causing some delay and inconvenience; and

to remedy this difficult-y is the ject of the. 1

present invention. To this end-,I provide one additional fold member, by placing in the fold f a folding line 0 nearer the free side of the foid, thus virtually making another fold member 7, and I place the securing means 11) preferably a little higher up and closer together, preferably passing-them through all the arts 6, f and f. With this construction, w en the box is grasped, as shown in Fig. 5, the outward pull of' the corner folds f on the folds f and 1" causes the end portions of the latter to turn toward a position substantially at right angles to the folds f,' thus effectually locking them in position and preventing the accidental collapse of the box, while not in any way interfe'ring with its being purposely collapsed or erected.

While I have shown the corner portions f and f as being folded inside the-box and the engaging folds f and f", likewise inside the box to engage the corner portions, it will be rea i'ly understood that the corner portions mightbe folded outside the box and the engaging folds likewise placed on the outslde to engage them,;in which-case the box would bev colla sed inwardlyand the folds f and f woul resist the tendency to collapse in that direction.

Whil -I have shown myinvention as em-' bodied in the form which I at present consider best adapted to carry out 1t s.purposes. it will be. understood that it is capable of modifications, especially in the construction of the. corner folds, and that I do not desire to be .imited in the interpretation of the followi g claim exceptasmay be neee-sjsitatd by the state of the prior art, lVhat I claim asnew, and desire to secure by Letters Patentof the United States, is: A box having a bottom, sides, ends and corner portion, extensions on said sides folded to form a double fold and secured to the sideswith theends of 'the, folds over lyingt he cornei port-ions, said folded ex- Tn wihmss whereof, I have hereunto set tenslons adapted tounfold partially to form my hand and affixed my seal, this 22nd day 1 a hook to engage the corner portions and of June A.
